[0002] With the development of society and the aging of the population, the demand for barrier-free facilities is growing. Traditional barrier-free toilet designs often rely on physical structural modifications, such as widening door frames and installing handrails, but these modifications do not fully take into account the special needs of the visually impaired. For example, when blind people use traditional barrier-free toilets, they still need to rely on touch and hearing to identify the environment, which is not only inefficient, but also poses health and safety risks, which increases the risk of infection or accidents such as collisions and slips.

[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0022] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The main solution of the embodiment of the present application is: when a visually impaired person is detected, the information of facilities to be used in the current facility area is obtained; based on the information of facilities to be used, corresponding instruction voice and lighting control information are generated; based on the lighting control information, the lighting equipment is controlled to generate corresponding visual signals, and the instruction voice is broadcast at the same time to guide the visually impaired person.

[0024] In this embodiment, the visually impaired person guiding device in the barrier-free toilet is used as the execution body. For the convenience of description, it will be explained as "device" hereinafter.

[0025] In the related art, a voice prompt function is usually used to provide voice guidance to the visually impaired in the barrier-free toilet, instructing the visually impaired to go to the sanitary facilities. However, the method of relying solely on voice prompts is limited to broadcasting the approximate location of the facilities, resulting in insufficient guidance accuracy for the visually impaired.

[0026] The present application provides a solution to provide comprehensive guidance for users with different degrees of visual impairment, thereby improving the accuracy of guidance for the visually impaired, and further providing comprehensive guidance services to improve user experience.

[0027] From the above embodiments, it can be seen that after detecting a visually impaired person, the present application obtains the information of the facilities to be used in the current facility area; based on the information of the facilities to be used, generates corresponding instruction voice and lighting control information; based on the lighting control information, controls the lighting equipment to generate corresponding visual signals, and simultaneously broadcasts the instruction voice to guide the visually impaired person. It is understandable that after detecting a visually impaired person, the present application provides comprehensive guidance for users with different degrees of visual impairment by broadcasting instruction voice in conjunction with the visual signals generated by the lighting equipment, thereby improving the guidance accuracy for the visually impaired person, and further providing a comprehensive guidance service to improve the user experience.

[0028] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a terminal system, etc. that can realize the above functions. The following takes the visually impaired person guidance device in an accessible toilet as an example to illustrate this embodiment and the following embodiments.

[0029] Based on this, the embodiment of the present application provides a method for guiding visually impaired people in an accessible toilet, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for guiding visually impaired people in an accessible toilet of the present application.

[0030] In this embodiment, the method for guiding visually impaired people in barrier-free toilets includes steps S100 to S300: Step S100, when a visually impaired person is detected, information of facilities to be used in the current facility area is obtained; It should be noted that the visually impaired refer to those whose vision is limited and who find it difficult to carry out daily activities like people with normal vision. It is usually used to describe those with visual impairments, including those with total blindness and partial vision loss.

[0031] In a specific implementation, the device detecting a visually impaired person means that the device recognizes that a visually impaired person approaches or enters a certain facility area through relevant means (such as sensors, cameras, sound recognition, etc.), and the facility area is preferably a toilet or an accessible toilet.

[0032] It is understandable that the facility information to be used refers to relevant facility information that is idle in the facility area and can be used by the visually impaired, including but not limited to the location, status and usage of toilets, toilets, washbasins, etc.

[0033] Step S200, generating corresponding instruction voice and lighting control information based on the facility information to be used; In a specific implementation, the device generates corresponding voice instructions based on the information of the facilities to be used. These voice instructions will tell the visually impaired how to reach the destination, such as "go straight for 10 meters, then turn left". In addition to the voice instructions, the device will also control the lights to assist navigation. For example, the device will light up the LED lights on the path to the destination, or use light beams to guide the visually impaired forward. The specific method of controlling the lights is also included in the facility light control information.

[0034] In the specific implementation, when the device detects a visually impaired person, it first determines the equipment to be used in the current facility area that can be used by the visually impaired person, and then conveys the location information of all the equipment to be used to the visually impaired person through voice and light, so that the visually impaired person can reach the destination without groping on his own.

[0035] In a specific implementation, the step of generating corresponding instruction voice and lighting control information based on the facility information to be used includes: Receive the voice information input by the visually impaired person, and extract the required facility information from the voice information; determine the target facility information based on the required facility information and the facility information to be used; and generate corresponding instruction voice and lighting control information based on the target facility.

[0036] In a specific implementation, the device first receives voice information, that is, the device receives voice information spoken by the visually impaired through voice recognition technology. The visually impaired can express their needs by speaking, such as "I need to find the nearest toilet." Secondly, the device extracts the required facility information, that is, the device analyzes the received voice information and extracts the specific facility information required by the visually impaired. In the above example, the device will identify "the nearest toilet" as the required facility.

[0037] In a specific implementation, the device determines the target facility that meets the needs of the visually impaired person based on the extracted required facility information and the available facility information in the current environment. For example, the device determines the nearest vacant toilet as the target facility.

[0038] Furthermore, the device generates voice instructions to tell the visually impaired how to reach the target facility. These instructions are customized according to the location of the visually impaired person and the location of the target facility, such as "go straight ahead for 5 meters and then turn right". The device also generates light control information, that is, in addition to voice instructions, the device also generates light control information to guide the visually impaired by controlling the LED lights on the ground or wall. These lights can form a light path to guide the visually impaired in the right direction.

[0039] It is understandable that the above process is real-time interactive, that is, the process is real-time, and the device will continue to monitor the voice feedback of the visually impaired to provide further guidance or adjustment instructions. The design of this application is to provide a navigation method for the visually impaired without visual participation through voice recognition and intelligent navigation technology, so that they can move more independently and safely in the environment. This system can be applied to various public places, such as shopping malls, airports, hospitals, etc., to improve the quality of life and social participation of the visually impaired.

[0040] Step S300, based on the lighting control information, controlling the lighting equipment to generate corresponding visual signals, and simultaneously broadcasting the instruction voice, so as to guide the visually impaired person.

[0041] In the specific implementation, the device generates corresponding lighting control instructions based on the previously determined target facility information. These instructions will tell the lighting equipment how to operate, such as which lights need to be turned on, the color and brightness of the lights, etc., that is, the device generates visual signals. Specifically, according to the lighting control information, the lighting equipment generates corresponding visual signals. These signals are LED lights on the ground lighting up to form a light path, or indicator lights on the wall flashing to indicate the direction.

[0042] Furthermore, the device also broadcasts instruction voices, that is, the device also broadcasts the instruction voices generated previously, providing voice navigation for the visually impaired. These voice messages will tell the visually impaired the direction and distance they need to go. Finally, the device guides the visually impaired by using visual signals and voice broadcasts at the same time. In this way, even if the visually impaired cannot see the light signals, they can understand the direction they should go through voice prompts.

[0043] It is understandable that the design purpose of this application is to provide more comprehensive and accurate navigation assistance to the visually impaired by combining visual and auditory sensory information, helping them to move safely and conveniently in public spaces. This multimodal navigation method can improve the accuracy and reliability of navigation and reduce the troubles and risks encountered by the visually impaired during movement.

[0044] In a specific implementation, the step of controlling the lighting equipment to generate a corresponding visual signal based on the lighting control information includes: The real-time position of the visually impaired person is obtained; based on the lighting control information, the facility lights of the corresponding facilities are controlled to generate a flashing prompt visual signal, and based on the real-time position, the electronic blind sidewalk lights are controlled to generate a dynamic road guidance visual signal.

[0045] It should be noted that the electronic blind spot light is a kind of intelligent auxiliary equipment designed specifically for the visually impaired, aiming to improve their travel safety and convenience. The electronic blind spot light emits a light beam through a preset spotlight to form a light path, or the indicator light on the wall flashes to guide the direction.

[0046] In the specific implementation, the device uses relevant positioning technologies (such as GPS, Bluetooth beacons, Wi-Fi positioning or ground sensors, etc.) to determine the current location of the visually impaired person in the environment, and controls the lighting equipment near specific facilities (such as toilets, etc.) to produce flashing prompts based on the previously generated lighting control information. This visual signal can attract the attention of the visually impaired and tell them the location of the target facility.

[0047] Furthermore, the device also controls the electronic blind sidewalk lights (a special ground lighting system) to dynamically adjust the light signals according to the real-time position changes of the visually impaired. These lights can form a light path to guide the visually impaired along the correct path. And as the visually impaired move, this will continuously update their location information and adjust the signals of the facility lights and electronic blind sidewalk lights in real time to ensure the accuracy and real-time nature of the guidance information.

[0048] It is understandable that the purpose of this application is to provide a continuous and dynamic navigation experience for the visually impaired, helping them to move safely and confidently in the environment. By combining visual signals and real-time location information, the system can provide an intuitive and easy-to-understand navigation method, reduce the difficulties and risks encountered by the visually impaired during the navigation process, thereby improving the guidance accuracy for the visually impaired, and then providing a comprehensive guidance service to improve the user experience.

[0049] In the specific implementation, refer to Figure 2 This application proposes a comprehensive intelligent voice prompt system for barrier-free toilets, which consists of three main parts: device side, local intelligent algorithm and cloud management platform. These three parts work together to provide all-round assistance and safety protection for the visually impaired. The details are as follows: 1. Device side: The device side is the core component of the entire system, directly interacting with the user and performing various functions.

[0050] Key features include: a) Configurability: Through the DIP switch, the device can be configured as different facility types (such as toilets, wash basins, etc.). This flexibility allows the same hardware to be used in a variety of scenarios.

[0051] b) Adaptive function: According to the dial setting, the device will automatically switch the corresponding voice recognition and interaction logic. For example, when set to toilet mode, the device will enable specific voice commands and responses related to the toilet.

[0052] c) Self-organizing network capability: The device has an automatic pairing function and can establish a connection with related auxiliary equipment (such as electronic blind paths). This ensures the coordination and consistency of the entire system.

[0053] d) Multimodal output: The device is equipped with sound prompts, LED indicator lights, and electronic blind spotlights to meet the needs of users with different degrees of visual impairment.

[0054] e) Emergency response function: The device can detect emergency situations (such as the user's call for help) and trigger local sound and light alarms.

[0055] Hardware composition: High-sensitivity microphone: used to accurately capture the user's voice commands and calls for help; speaker: plays voice prompts and alarms; LED indicator: provides visual guidance and warnings; processing chip: runs local algorithms, handles voice recognition and device control logic; communication module: used for self-organizing network communication between devices and data exchange with the cloud platform; relay (component): controls external alarms and other equipment; power system: supports both lithium battery power supply and power adapter power supply, and realizes intelligent power management.

[0056] 2. Local algorithm: The local algorithm is the intelligent core embedded in the device, responsible for processing various input signals and making corresponding responses.

[0057] Key features: a) Speech recognition and understanding: Process user speech input in real time and understand user intent; b) Situational awareness: Select appropriate response strategies based on the configuration and current status of the device; c) Equipment coordination: managing the collaboration with other paired equipment (such as electronic blind paths); d) Emergency situation determination: Analyze audio input and identify emergency situations; e) Local decision-making: In an emergency, a decision to trigger a local alarm is made quickly; f) Platform command processing: receiving and processing cloud platform commands.

[0058] 3. Cloud device management platform. As the hub of the entire system, the cloud platform is responsible for advanced data processing, remote management and information distribution.

[0059] Key features: a) Device management: Remotely monitor and manage all connected devices, including configuration updates and status monitoring; b) Data analysis: collect and analyze usage data to provide a basis for system optimization; c) Emergency response coordination: Receive emergency alarms from the device side and coordinate response actions; d) User management: manage the accounts and permissions of security personnel and maintenance personnel; e) Report generation: automatically generate event reports and usage statistics; The system workflow includes: 1. User interaction: When a blind user enters the restroom and asks about the location of the facilities, the nearest device captures the voice through a microphone, and the local algorithm performs speech recognition and intent understanding.

[0060] 2. Device response: After identifying the user's needs, the corresponding device (such as a toilet device) is activated. The device emits a sound prompt and the LED indicator starts flashing. If there is a paired electronic blind path, it will also be activated to provide additional guidance.

[0061] 3. User guidance: The user follows the sound and light to move towards the target. The system continuously monitors the user's position and emits an arrival prompt sound when the user approaches the target.

[0062] 4. Emergency handling: If an emergency is detected (such as a call for help), the device immediately triggers a local sound and light alarm. At the same time, the alarm information is sent to the cloud platform. The cloud platform immediately notifies relevant personnel (security administrators, supervisors, etc.). The system records the event details, including time, location, and event type.

[0063] 5. Continuous monitoring and improvement: The cloud platform continuously collects usage data and event records. These data are used for system performance analysis and continuous improvement.

[0064] In specific implementation, through this comprehensive and integrated solution, this application not only solves the practical difficulties faced by visually impaired users when using public toilets, but also provides a scalable and intelligent solution, greatly improving the safety and ease of use of barrier-free facilities.

[0065] In the related art, a voice prompt function is usually used to provide voice guidance to the visually impaired in the barrier-free toilet, instructing the visually impaired to go to the sanitary facilities. However, the method of relying solely on voice prompts is limited to broadcasting the approximate location of the facilities, resulting in insufficient guidance accuracy for the visually impaired. In comparison, after detecting the visually impaired, the present application obtains the information of the facilities to be used in the current facility area; based on the information of the facilities to be used, generates corresponding instruction voice and lighting control information; based on the lighting control information, controls the lighting equipment to generate corresponding visual signals, and broadcasts the instruction voice at the same time to guide the visually impaired. It is understandable that after detecting the visually impaired, the present application provides comprehensive guidance for users with different degrees of visual impairment by broadcasting instruction voice in conjunction with the visual signals generated by the lighting equipment, thereby improving the guidance accuracy for the visually impaired, and further providing a comprehensive guidance service to improve the user experience.

[0066] Based on the above first embodiment, the present application also proposes another embodiment, referring to Figure 3 , the method for guiding the visually impaired in the barrier-free toilet includes: In a specific implementation, the step of generating corresponding instruction voice and lighting control information based on the facility information to be used includes: Step A100, obtaining the vision level information of the visually impaired person; In a specific implementation, the step of obtaining the vision level information of the visually impaired person by the device includes: When the visually impaired person places the disability certificate on a preset certificate reading device, the certificate information read by the certificate reading device is received; and the vision level information of the visually impaired person is extracted from the certificate information.

[0067] It should be noted that the vision levels are usually classified according to certain standards, such as the World Health Organization (WHO) classification of visual impairment, or the classification standards of each country. These levels are divided into complete blindness, severe visual impairment, moderate visual impairment and mild visual impairment.

[0068] In a specific implementation, the device can obtain vision level information in a variety of ways, including but not limited to: personal information entered by the user when registering the system; automatic acquisition through connection with the electronic health records of medical institutions; data uploaded by auxiliary devices used by the user (such as smartphones or smart glasses); real-time provision by the user through voice commands or other interactive methods.

[0069] In specific implementations, regarding the application of vision level information, after obtaining the vision level information, the device can: adjust the speaking speed and volume of voice prompts to adapt to the user's hearing and comprehension ability; adjust the brightness and flashing frequency of light signals to ensure that the user can see and understand these signals; provide navigation paths suitable for the user's vision level, such as selecting wider and clearer paths for people with severe visual impairments; provide users with customized auxiliary services, such as providing detailed voice descriptions for completely blind users and visual aids for low vision users.

[0070] It is understandable that the device obtains the vision level information of the visually impaired in order to provide more accurate and effective auxiliary services, ensure that they can better use the navigation system, and improve their quality of life and independence.

[0071] Step A200, determining corresponding speech weight and light weight based on the vision level information; In a specific implementation, the device will adjust the intensity and method of the auxiliary information provided to the visually impaired person according to the degree of visual impairment (i.e., vision level information). Specifically, the vision level information includes information such as whether the visually impaired person is completely blind, has partial vision loss, or is color blind, as well as the degree of their vision loss. This information helps the device understand the specific needs of the user.

[0072] Furthermore, the voice weight is determined by the device according to the vision level, and the size of the voice weight will affect (increase or decrease) the frequency or clarity of the voice prompts to ensure that the visually impaired can hear and understand the navigation instructions. For example, for users with severe visual impairments, the device will provide more detailed and more frequent voice prompts. Similarly, the device will adjust the brightness or flashing mode of the light signal based on the light weight to meet the needs of users with different visual impairments. For example, for users with low vision, brighter or more frequently flashing light signals are needed to guide them.

[0073] Step A300: Generate corresponding instruction voice and light control information based on the facility information to be used, the voice weight and the light weight.

[0074] In a specific implementation, the device will allow the visually impaired to adjust the intensity of voice and light signals according to their vision level and personal preferences. Such personalized settings can improve the usability and satisfaction of the navigation system.

[0075] Understandably, this adjustment based on vision level information is intended to provide more customized and effective assistance to the visually impaired, helping them to better navigate space and carry out daily activities. For example, some smart glasses systems use artificial intelligence technology to capture the surrounding environment through cameras and provide voice feedback to assist the daily life and travel of the visually impaired. In this way, the system can provide more accurate and personalized assistance services for the visually impaired.

[0076] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method for guiding visually impaired people in barrier-free toilets of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0077] Based on the above first and second embodiments, the present application also proposes another embodiment, referring to Figure 4 , the method for guiding the visually impaired in the barrier-free toilet includes: In a specific implementation, after a visually impaired person is detected, before the step of obtaining information of facilities to be used in the current facility area, the method includes: Step B100, collecting portrait information of a preset area; In a specific implementation, the device is equipped with a camera or other image acquisition device in a specific area (preset area) to capture images or portrait information of all persons entering the area.

[0078] Step B200, extracting feature information from the portrait information, and sending the feature information to a preset portrait detection model; In a specific implementation, the device extracts key features from the collected portrait information, such as facial features, body posture, etc. These feature information will be used in the subsequent portrait recognition process.

[0079] Step B300, detecting the feature information by using the portrait detection model to obtain a portrait detection result, and judging whether the target user in the portrait information is a visually impaired person based on the portrait detection result; In a specific implementation, the device sends the extracted feature information to a pre-set portrait detection model. This model is an artificial intelligence-based algorithm, such as a deep learning network, for analyzing the feature information.

[0080] Furthermore, the portrait detection model processes the feature information to obtain the portrait detection result, which includes portrait matching degree, identity recognition and other information.

[0081] Step B400: If the target user is a visually impaired person and trigger information indicating that the target user enters a designated area is received, it is determined that a visually impaired person is detected.

[0082] In a specific implementation, the device determines whether the target user in the captured portrait information is a visually impaired person based on the portrait detection result. This involves comparing the portrait information of known visually impaired people in the database, or identifying specific auxiliary equipment (such as guide dogs, canes, etc.). If the system receives trigger information that the target user enters a designated area (such as a sensor signal set up in an accessible toilet), and confirms that the user is a visually impaired person through portrait detection, the device will determine that a visually impaired person is detected.

[0083] It is understandable that the above process uses portrait recognition technology to automatically detect visually impaired people in order to provide them with customized services or assistance. The application of this technology can improve the timeliness of care and services for visually impaired people and make it more convenient and safe for them to use public facilities or services.

[0084] In another embodiment, the device detects the feature information through the portrait detection model, and in addition to obtaining the portrait detection result, can also predict the vision level information of the visually impaired person in the portrait detection result. Specifically, before the device detects the feature information through the portrait detection model to obtain the portrait detection result, the method further includes: Acquire portrait feature samples, vision level labels of the portrait feature samples, and portrait detection result labels of the portrait feature samples; iteratively train a preset model to be trained based on the portrait feature samples, vision level labels, and portrait detection result labels to obtain a portrait detection model.

[0085] Furthermore, based on the above embodiment scheme, it is also proposed: obtaining the time label of the portrait feature sample, and determining the time weight based on the time label, wherein the time weight reflects the current light intensity (the light intensity is higher in the morning and afternoon, and the light intensity is low at night); based on the portrait feature sample, the vision level label, the portrait detection result label and the time weight, iteratively training the preset model to be trained to obtain a portrait detection model.

[0086] In the specific implementation, the present application takes into account that the portrait information captured at different time points is affected by external environment such as light. For example, when the light is dark at midnight, the clarity of the portrait information captured is lower than that during the day. Therefore, time weight is added during feature recognition. When the shooting clarity is high, the time weight is small, and when the shooting clarity is low, the time weight is large.
